Some Things To Consider As You Choose Your Envirolet® System

Power Choices

  • All Envirolet® systems are available in 12VDC and AC Electric. Some systems are available Non-Electric.
  • We recommend to opt for an AC Electric system if power is available for best performance and the highest capacity.

Waterless or Low Water

  • There are waterless and low water flush systems available.
  • The choice can be a personal preference or may be dependent on certain installation requirements.
  • Waterless systems either install directly on bathroom floor or directly below the floor.
  • Low Water systems can gravity flush to the composting system below (directly below or off-set).
  • FlushSmart VF vacuum flush systems can flush horizontal (sideways!) up to 70ft away and 12ft vertical (up!).
  • Check out our buying guide for more info.

Parts & Accessories

  • All systems come with what is required for a basic installation (except for rigid 4" vent pipe to complete the venting in remote systems or extra lengths of venting, draining, etc. materials needed for some installations).
  • At time of system purchase it is a good idea to consider adding some accessories such as soil additives (Compost Accelerator, Compost Power, Daily Mix, etc.) to save on future shipping costs.


  • Shipping is included in the price for all complete Envirolet® Composting Toilet Systems, unless specified (for certain special promotions, etc.).
  • Parts are shipped for a flat-rate S&H price unless otherwise noted.
  • There will be extra charges to Alaska,Hawaii and "remote" locations (islands, etc.) due to the increased shipping costs.
